Now that my T90 rebuild project is done, I'm turning to the D18 transfer case. I've never cracked open a transfer case before, so this is a new adventure for me.
The first roadblack was the parking brake drum - it wouldn't come off. This thing was very rusty, I couldn't event retract the brake shoes. I had to make a puller to get the drum off. It worked great. I spent most of the afternoon working on it. The pivot pin for the shifters was frozen solid. I finally resorted to oxy/act torch to heat up the case enough to drive it out - what a bear! I still have more disasembly to do and there is a broken off oil pan bolt I have to get out. But after a good 4 hours of fighting with it, I'm done and ready for a cold one! |

That 27-LED portable work light is the best thing Harbor Freight ever gave away. Nice work on the Xfer case.

There's a reason it's called Ol' Unreliable

Thanks guys. I've seen RFP's double lip seal mentioned before - sounds like a great idea. I'll keep it in mind come parts ordering time.
The parking brake shoes, backing plate and drum are in really bad shape. The shoes were completely rusted away in some places, the backing plate it almost rusted through. Fortunately, I have another TC in the shed that is grease caked. So I should be be able to use the brake parts of it. I may end up tearing that one down too. Those little 27 LED Harbor Freight lights are very handy. I find them especially useful on my parts washer. I stick two of them inside the lid so I can see what I'm cleaning.

I'm about to the point where I need a special tool to drive the bearing forward on the output shaft. The original tool was a heavy fork-like thing.
Rick Stivers made one from a hatchet. Not quite the same, but it worked. Short of making a similar tool from a hatchet, does anyone know of another way to do this, or another commonly available tool? |

I make a puller that specifically deals with that bearing if you're interested.

The hatchet thing seems like a fairly simple solution. But please tell me more about your puller. Do you have a photo?

Puller is two halves that bolt together to capture the bearing and another tow fasteners retain it to the side of the case through the existing front housing holes. You then press or tap the shaft out. Cost is $55+shipping. I have them in stock.

Wow - that's a neat tool Joe. I'm going to look close at it tonight and determine my way ahead. I'll let you know. Thanks

And less than the axe head and emergency room visit required to make the other one.

You got that right I contacted Joe, he'll be sending a tool asap I got most of the disassembly done tonight except the output shaft and the front yoke seal. Even with the front cap off and disassembled, that seal is in there tight (I'm aware if the lip behind it). So I soaked it with PB Blaster and will work on it tomorrow night.

I got the TC completely disassembled today. Joe's tool worked great, but it was a challenge. The bearing was on tight, I had to use the hydraulic press to get it to move. Then I could finally get to the hidden snap ring.
I ran everything through the parts washer for an inital cleaning. Next will be a detailed inspection on each piece. Then I'll be making a list and checking it twice.... The parking brake was badly corroded, so I pulled another TC from the shed and pulled the brake drum, backing plates and parts off to use. This TC has a busted case, but plenty of good parts on it. I'm new to making videos, but here is a clip of what I've been doing. Edited by ndnchf - 23 Dec. 2018 at 1:40pm |

Well crap - I'm at a work stoppage. I was getting parts cleaned up for paint when I found the rear bearing cap is cracked. Grrrr... does anyone have a spare laying around? I'll post a WTB ad.

The rear cap on my 3B was cracked like that. I had no spare parts back then, and needed the jeep for hunting, so I vee'd the crack and brazed it up, filed it smooth and put it on. A good enough temporary repair. Twenty-plus years later, it's still doing fine. BW

All repairs are temporary, until such a time as they work... and become permanent (a good repair is good, and NOT to be confused with Bubba Weldit )
